The radiological appearance of mostly broad-based polyps in the rectosigmoid was studied in 35 patients. In all patients the diagnosis was histologically confirmed after surgical treatment. Conclusions on the histological tumour status could not be drawn either from surface structure, broadness of base and retraction of base, or from the base/height ratio. Stenosing growth, however, was seen relatively more often with carcinomas than with benign lesions. The discovery and identification of five carcinomas having a size of up to 2 cm illustrates the need for complete removal and histological processing of even seemingly negligible residues of polypous processes in the rectosigmoid.
对35例患者直肠乙状结肠中大多为广基息肉的放射学表现进行了研究。所有患者在手术治疗后经组织学确诊。无论是从表面结构、基底部宽度和基底部回缩情况，还是从基底/高度比，均无法得出关于组织学肿瘤状态的结论。然而，与良性病变相比，狭窄性生长在癌中相对更常见。发现并识别出5例直径达2 cm的癌，这表明即使是直肠乙状结肠中看似微不足道的息肉样病变残留也需要完整切除并进行组织学处理。
